As shown in the figure a particle is placed at O in front of a plane mirror M. A man at P can move along path PY and PY' then which of the following is true

Options:

Answer:

Solution:

Put O at the origin; the mirror runs from $(- d, 0)$ to $(0, d)$ along $y = x + d$ .

Image of O is at ( $- d, d$ ).

Rays from the image through the mirror points go right and downward, or horizontal at the top edge.

So the visible region lies at or below $y = d$ .

On PY' every point is visible; on PY only up to height $d$ .

Ans. (C)
